Synthesis of Chiral Trifluoromethyl-Substituted Hydrazines via Pd-Catalyzed Asymmetric Hydrogenation and Reductive Amination

open access: yesACS Catalysis, 2015
An efficient approach toward the synthesis of cyclic and linear chiral trifluoromethyl substituted hydrazines was developed by Pd-catalyzed asymmetric hydrogenation of both N-acyl and N-aryl hydrazones in excellent yields and up to 97% ee.

Spectrophotometric Determination of Hydrazine

Analytical Letters, 2007
Hydrazine is determined spectrophotometrically by forming the derivative 2,4-dinitrophenylhydrazine from 2,4-dinitrochlorobenzene. The formed dinitro derivative undergoes condensation reaction to form the hydrazone with p-dimethylaminobenzaldehyde (p-DAB).

Microanalysis of hydrazine-monomethyl-hydrazine mixtures

Microchemical Journal, 1964
Abstract The analysis of hydrazine-monomethylhydrazine mixtures has been a complicated and time-consuming procedure ( 3 ) that is not suitable for large numbers of microsized samples. A simple, selective method which combines the well-known iodate titration ( 4 ) with a gas Chromatographic separation ( 2 ) affords a precise and accurate determination

Hydrazine

Reactions Weekly, 2000
Abstract Hydrazine is a clear, colorless hygroscopic liquid used primarily in the manufacture of rocket propellants; lesser amounts are used in the manufacture of agricultural chemicals (e.g., maleic hydrazide), plastic foams, soldering fluxes, herbicides (e.g., 3-amino-1,2,4-triazole), and medicinals (e.g., the antitubercular agent ...
